I feel like I'm just his babymama...

I've been with my boyfriend for 2 years and we recently just had a baby 3 weeks ago. A couple weeks before I had her, we had stopped kissing or having sex because he didnt want to. It really bothers me, it makes me feel unwanted and unattractive to him. I know we arent supposed to have sex yet but still. I havent really tried to talk to him about it recently because when I was pregnant I would annoy him about it everyday. I just dont know. Maybe I'm overreacting 😕 I just want him to want me. I mean I've lost almost 30 pounds and I only gained 22 while pregnant. I feel like I look good. He says hes attracted to me but I dont feel wanted. Am I overreacting?
